1.1 is not supposed to generate anchors for section titles, but it does

According to

http://maven.apache.org/doxia/references/doxia-apt.html#Anchors_for_section_titles

"Contrary to the original APT format, section titles are not implicitly defined anchors. If you want an anchor for a section title you need to define it explicitly as such:"

However, Doxia does generate anchors for section headers.

This is clear from the URL above; the underlying HTML is:

<h4><a name="Anchors_for_section_titles">Anchors for section titles</a><a name="Anchors_for_section_titles"></a></h4>

Compare with the code for

http://maven.apache.org/doxia/references/doxia-apt.html#Enhancements_to_the_APT_format

at the top of the page, and then compare with the APT source:

http://svn.apache.org/viewvc/maven/doxia/site/src/site/apt/references/doxia-apt.apt?revision=985438&view=markup

which does not have {} round the initial section header, yet the anchor is still generated.

Headers with {} around them have 2 anchors.
